Intratumoural injection with iNSA/E6E7^equ and/or iNSB/E6E7^equ led to tumour regression even in equine patients with severe disease.

A mare (ANC) with multiple, severe-type sarcoids affecting the right axilla, abdomen and inner thigh responded to intratumoural therapy. Injection of a single lesion with iNSA/E6E7^equ on days 0, 2 and 4, and iNSB/E6E7^equ on days 7, 9 and 11 by (white arrow indicates injection site) led to complete regression of the injected and all non-injected sarcoids within 13 months as exemplarily shown for the right axilla. d0: day 0; m4: month 4; m10: month 10; m13: month 13.
